The Tinkering Tangle: My attempt at a bespoke ‘smart’ door handle

So, I’ve finally reached that stage of the tinkering hobbyist and admitted it: my workspace is no longer a functional surface for actual tasks. It’s currently a graveyard of half-finished projects, tangled cables, and a very specific, rather alarming amount of 3D-printed parts that don’t quite fit together on first try. I suppose if you want to ‘make’ something, you have to accept the chaos of the process.

I’ve been obsessing over this latest project—a sort of ‘smart’ door handle mechanism for a cupboard in the hallway. It sounds ridiculous, and honestly, it might be just a waste of time, but I do enjoy the logic puzzles involved. I managed to get the Raspberry Pi hooked up to a motor and trying to figure out why the latch won’t engage properly. Some of those little 3D-printed gears are so beautiful and haveer (I think that’s how it sounds) are currently sitting in a pile of ‘needs fixing’.

The struggle with the filament

One thing I really struggled with today was the print quality of some of thes000 gears. There were severalerbs are actually quite a bit more complex than they seem to like trying to figure out why the gears aren’t engaging correctly and I had to re-re-print again. The 3D printer is a bit temperamental, but it’s a keep-mocker but it keeps making some bits that just won’t work because of the just being a little bit more complex than they seem. It’s a lot of many layers.
